Write an equation in slope-intercept form to represent the relationship in the table below.
Answer:
[tex]y=2x+3[/tex]
Step-by-step explanation:
Choose 2 ordered pairs from the table: (0, 3) and (5, 13)
Let [tex](x_1,y_1)[/tex] = (0, 3)
Let [tex](x_2,y_2)[/tex] = (5, 13)
Use the slope formula to find slope: [tex]m=\dfrac{y_2-y_1}{x_2-x_1}[/tex]
[tex]\implies m=\dfrac{13-3}{5-0}=2[/tex]
Use point-slope form of linear equation to find equation:
[tex]\implies y-y_1=m(x-x_1)[/tex]
[tex]\implies y-3=2(x-0)[/tex]
[tex]\implies y=2x+3[/tex]
What is the equation for the graph shown?

Can someone pls explain their own way of solving gcf and lcm I’m very stuck HELP!
Answer:
okeyy
Step-by-step explanation:
Greatest Common Factor
- first list all the numbers that could be multiplied to the factors given.
30 = 1, 2, 3, 5, 6, 10, 15, & 30
24 = 1, 2, 3, 4, 6, 8, 12 & 24
- then you find the common number between them but the highest one (which is 6)
Least Common Multiple
- so we could say this is the opposite of the greatest common factor
3 = 3, 6, 9, 12, 15, 18
4 = 4, 8, 12, 16, 20
- in here i listed the multiples of 4 & 3 and got the least common between them (which is 12)
Answer:
tbf i wouldnt get this if i read this for the first time
Step-by-step explanation:
write numbers down
draw a branch to split the number into a prime and the number it needs to multiply to get to it
e.g. 156 can split into
/ \
2 78
kee.p splitting the number.s
78 = 2, 39
39 = 3, 13
now do the same for the second number
e.g. 188
/ \
2 94
94 = 2, 47
draw a venn diagram
put the numbe.rs in the correct locatio.n
a repe.at number e.g. 2, 2, 2, 2 now wo.uld be two 2s because they essential.ly cancel each other out
156 188
13, 3 2, 2 47
for gcf you would times the number in the centre
2 x 2 = 4
4 is the gcf
for lcm you would times everything in the venn diagram
13 x 3 x 2 x 2 x 47 = 7332
7332 is lcm

sally can paint a room in 3 hours while it takes steve 8 hours to paint the same room. how long would it take them to paint the room if they worked together ?
Answer:
2 hours 11 minutes
Step-by-step explanation:
Each hour Sally can paint 1/3 rooms, Steve can paint 1/8 rooms.
If they work together, each hour they can paint 1/3 + 1/8 = 11/24 rooms.
So They will take 1/(11/24) = 24/11 = 2.18 hours to paint a whole room.
2.18 hours = 2 hours 0.18*60 minutes
0.18 * 60 = 11
Answer: 2 hours 11 minutes

What is the mode???? Thank you math experts I will mark brainliest
Answer:
median: 51
mode: 51
Explanation:
given:
43, 55, 51, 62, 64, 38, 35, 45, 51
arrange them in increasing order:
35, 38, 43, 45, 51, 51, 55, 62, 64
now find median, the number which is at the middle:
51 is the median
now find the mode, the number which appears most times:
51 is the mode
Answer:
C
Step-by-step explanation:
I also see median right there which that would also be C(51)
The mode is C(51) because the mode is the number that appears the most and as you see 51 appears 2 while no other number appears twice.

The sound wave of two music notes can be represented by the function y = 2cos2x and y = −cos x, where x represents the time since the note is played. At what times will the frequencies of the sound waves be the same in the interval [0°, 360°)?
x = 0°, 60°, 180°, 300°
x = 0°, 120°, 240°, 180°
x = 60°, 90°, 270°, 300°
x = 90°, 120°, 240°, 270°
The sound waves are illustrations of cosine functions
The frequencies of the sound waves are x = 90°, 120°, 240°, 270°
How to determine the frequencies of the sound wavesThe equations of the sound waves are given as:
[tex]y = 2\cos^2(x)[/tex]
[tex]y =-\cos(x)[/tex]
Next, we plot the graphs of the functions [tex]y = 2\cos^2(x)[/tex] and [tex]y =-\cos(x)[/tex]
From the graphs of the functions (see attachment), we have the following x-coordinates of the points of intersection of the both curves between the interval [0°, 360°)
[tex]x =(\frac{\pi}{2},\frac{2\pi}{3},\frac{4\pi}{3},\frac{3\pi}{2})[/tex]
Express as degrees
[tex]x =(90^o,120^o, 240^o, 270^o)[/tex]
Hence, the frequencies of the sound waves are x = 90°, 120°, 240°, 270°

Assume that the weight loss for the first month of a diet program varies between 6 pounds and 14 pounds, and is spread evenly over the range of possibilities, so that there is a uniform distribution. Find the probability of the given range of pounds lost.
1) P(x = 7)
2) Between 8.25 po9unds and 12 pounds.
3) Greater than 10.50 pounds.
Please show work.
Hello!
For this uniform distribution, the shape of the density function is a line. We can begin by identifying key elements of the distribution:
Range: 6 to 14 pounds
Formula of density function:
y = 1/Range
1 - (14 - 6) = 1/8 = 0.125
f(x) = 0.125
1)
P(x = 7)
A uniform distribution is a continuous distribution, so the probability of x being an EXACT value is approximately 0.
This is the same as if we took the following integral. (Finding the area under a curve with the same start and end point)
[tex]\int\limits^a_a {f(x)} \, dx = 0[/tex]
Therefore, P(x = 7) = 0.
2)
We can think of this as finding the area of a rectangle.
The width would be the difference between 8.25 pounds and 12 pounds:
W = 12 - 8.25 = 3.75
The height would be the function (y = .125), or:
h = .125
Using the equation for the area of a rectangle: (A = h * w)
A = 3.75 * .125 = 0.469
Thus, P(8.25 < x < 12) = 0.469
3)
To find the probability GREATER than 10.50 pounds, we can subtract this value from the max value for the width:
W = 14 - 10.50 = 3.50
The height is the same as above:
h = .125
Solve for the area:
A = 3.50 * .125 = 0.4375
P(x > 10.5) = 0.4375

Answer:
-i

Just divide that power by 4

A storage container shaped as a rectangular prism can hold 896 wooden cube blocks with edge lengths of 14 ft.
What is the volume of the container?

pls helppppp ASAP!
Answer:
224
Step-by-step explanation:
The other person is my twin and thats right cause we were on the sam quiz
The volume of the container is 2,452,864 cubic feet.
What is a prism?A prism is a three-dimensional object.
There are triangular prism and rectangular prism.
We have,
The volume of a rectangular prism can be found by multiplying the length, width, and height of the prism.
We know that the container can hold 896 wooden cube blocks, each with an edge length of 14 ft.
This means that the total volume of the wooden blocks is:
V(block) = (14 ft)³ = 2,744 ft^3
To find the volume of the container, we need to divide the total volume of the wooden blocks by the number of blocks that can fit in the container.
We are told that the container can hold 896 wooden blocks, so we can set up the following equation:
V(container) / V(block) = 896
Solving for V(container):
V(container) = V(block) x 896
V(container) = 2,744 ft³ x 896
V(container) = 2,452,864 ft³
Therefore,
The volume of the container is 2,452,864 cubic feet.

Answer:
quotinet = 3x² - 2x - 2

Step-by-step explanation:
12x³ - 2x² - 12x + 3
= 3x²(4x + 2) - 6x² - 2x² - 12x + 3
= 3x²(4x + 2) - 8x² - 12x + 3
= 3x²(4x + 2) - 2x(4x + 2) + 4x - 12x + 3
= 3x²(4x + 2) - 2x(4x + 2) - 8x + 3
= 3x²(4x + 2) - 2x(4x + 2) - 2(4x + 2) + 4 + 3
= 3x²(4x + 2) - 2x(4x + 2) - 2(4x + 2) + 7
= (4x + 2)(3x² - 2x - 2) + 7
